Me and my buddies have used Selmons Custom Exhaust in Scarborough for about 5 years. He done custom exhausts for our Honda's, Talon's etc. The good thing about him is he provides warranty, ie. my brother cat was hitting speed bumps after he put in a different cat. Regardles of that Selmon took the car back up and fixed it for free. Plus he is trustworthy because he has two race cars himself (that whole pride in the work he does thing). Might be worth the call.
